When I add any link to text (in any text block) and click save, I'm not able to edit that text block anymore.

It only happens when I add links. I tried different ways but all seem to fail.

When I try to edit again, it doesn't show the editable text window/section. It only shows CSS animation options and extra class name, no editable text box.

Alternatively, how can I send a picture or quick video to you to explain?
